GMIPOSITION OF MATTER FOR SEALING- PNEUMAIIC TUBES.

all whom it may concern:

Be it known that I. ALIEN J. Rune-- noT'roM, of New Albany, in the county of Floyd and State of Indiana, have invented a. certain new and useful Improvement in Composition of Matter for Sealing; Pneumetic- Tubes, of which the following; a full, clear, and exact description.

My invention relates to that class of pueu matie tires in which a layer of plastic material, sur'u as raw unvuleunized rubber, is employed to not automatically in sealing punctures, and it consists in a composition of (minute, caueiio ball, and :reera flake which are mixed or mingled by heat (without vulrunization) and pressure, preferably in the form of sheets or strips of plus-tie materiel, suitable for use in the manufacture of 'iiir tubes for pneumatic tires, or in eouneetion therewith. i

in the menu 'aeture of my improved (zomposition, I prefer to use sixty (60} parts of ezunetu, twenty (20} parts of CtlllCllO Dali, and twenty (20) parts of acorn fluke, which Petentedl iFeli. E13, 1191?.

may be ground and mixed and then united into a plastic reuse or sheet, Without vulcanization. bynioderate heat and pressure in the manner well known to those skilled in the use and manipulation of rubber. It have found, after many and exhaustive experiments, that the foregoing comp-0- sitieu has many advantages over and is Sillifil'lfil' to other l'llllb l in the sealing of punctures in liPtHbQs for pueuuuitie tires. i-luviug thus described my im-eution, \Vlllti'eluiui :iuil ilrsire to secure by Lettors Fatent is As; a new article of mzmutueture, u eomposltiou of mutter vomposeil of rumetu, emu-ho lmll, :iurl uecm fluke, substantially us and for the purpose described.

in testimony whereof, I have hereunto set my luuul.
